Ventmn- This manual means comprises a shaft 2| pivot- 3 s a sectional view on the line 3-3 of ally supported within the interior of the automo Fig. bile body ID. This shaft 2| carriesa drum 22 4 is asectional view t i e 4-4 .Of upon which the free end of the cable l8 is'inounted. There is a drum 22 withinthe automobile body for each of the cables 58. A ratchet wheel 23 is mounted upon each of the shafts 2| to the front of the drums 22. Each of the ratchet wheels 23 is adapted to be engaged by a pivotally mounted pawl 24 mounted upon a stationary portion of the automobile body Hi. This pawl 24 engages the teeth of the ratchet wheel 2.3 in a manner to permit the drum 22 to be easily turned for winding the cable i ii thereon but preventing the cable from being unwound therefrom unless the pawl 24 is disengaged from the teeth of the ratchet wheel 23. Thus, the ratchet wheel and pawl act to hold the jack arms H3 in their raised position, see Fig. 3, and prevent the same from being lowered unless the pawl 2:2 is pivoted out and disengaged with relation to the ratchet wheel 23. The shafts 2| carry. handles 2| by which means they may be conveniently turned.

A latch is provided for preventing each of the jack arms from being lifted off the ground when itreach'es the lowered position, see Fig. 7. This latch comprises a casing 25 mounted upon the inside face of each of the housings I4. Each of the casings 25 has a slidably mounted bolt 26, the inner end of each projects into the housing It and bears against the end of the jack arm I6. Each of the bolts 26 has an outwardly eX- tending pin portion 21 provided with a loop. portion 27 at its extended end. A spring .23 is coaxially mounted upon the pin portion 21 and op erates between the end wall of the casing 25 of.

the adjacent end of the bolt 26 for urging the bolt into the housing 14. A cable 29has one of its ends attached to the loop member 27 and the other of its ends attached to its respective cable [8. Thus when the cables l8 are moved to-raise the jack arms It the bolts 26 will be. withdrawn from the housing H. The inner ends of the bolts 26 when the jack arms I6 reach .their low-}- the cutouts 30. Therefore each of the cables 29 is'provided at their intermediate portion with a spring 3! which is adapted to stretch as the.

cable 88 moves further after the bolt 26 has reached'its completely ejected position. stretching ofthis spring permits the jack armsv to be completely raised after'the bolts 26 have been completely ejected from the housing It;

Each of the jack arms i6 is provided with a.

means for permitting the automobile to be driven with a flat tire when the jack arm is in the opera ative position. This means comprises a retractable wheel 32 mounted within the inwardly extending cutout Ili formed in the bottom 0f the This wheel 32 is rotatively sup.-. ported between the arms of. the yoke 33 posi- A .pin 34 extendsv jack arm l6.

tioned within the cutout 55 between the arms of the yoke 33 and has a wheel 32 rotatively supported thereon. The inner end.

of the yoke 33 is connected toone end of a rod 35 slidably supported in a pair of spaced bearings' 36 mounted within cutouts 16 and spaced. from the bottom of the jack. arm l6. A collar. 31 is mounted upon the rod 35 between the bear- The ings 36. An expansion spring 38 is coaxially mounted upon the rod and operates between the lowermost bearing 35 and the adjacentface of the collar 31 for urging the rod 35 into a position in which the wheel 32 will be in a retracted posi' tion as shown in Fig. 4.

Adjacent the inner end of the rod 35 a shaft.

39 is rotatively supported between the side walls t of the jack arms it. This shaft 39- carries a cam M This cam 49 has .a cutout portion Mi engaged by a tail 16 formed on the interior of the jack arm [6 for limiting the distance through adapted to engage the inner end of the rod 35 when turned for urging the rod 35 downwards against action of the spring 38 to extend the 'wheel 32 as shown in Fig. 8. One end of the, shaftMl extends from the inner side of the jack r s 20 arm [43 and is connected to a flexible shaft M. This flexible ,shaft'M extends to theinteriorof "which the cam 4E may be turned. This cam 40 also has one thickened portion M which iS. Q

the automobile and is provided with. a knob 42. which may be turned to complementary turn-the Y shaft 4! to rotate thecam ti'i' as described.

In operating this device .it is necessary that v the'knobs' tz, berotated for extending the wheels 32 while the jack arms. it are in an inoperative position as shown in Figs. 3 and 7. If so oper J ated the wheels 32 will be extended and upon any forward movement of the automobile the 30 jack arm 16 willreach a. vertical position as shown in Fig. 8. With the wheel 32 engagingthe ground the automobile may be driven even though it might have a flat tire. -It is impossible to rotate the knob dz to extendthe wheels .32:

when the jack arms reach'their'operative position as shown in Fig. 8.

The operation of this device is as follows? If using the device as a theft prevention dee vice the pawl 24 is disengaged from the rachet wheels 23 and the handles Zi rotated. to rotate.

the drums 22 to unwind the cables l8 therefrom.

This movementof the cable I8 causes the jack arms E6 to be lowered until they reach the posi-' tion shown in Fig. '7. When they reachthisposition the bolts 26 will move into thehousing M and engage into the adjacent end of, the cutouts- 3!} formed in the jack arms it for preventing the jack arms from being lifted unless the cables} is are rewoundupon the drums 22.. With the jack arms engaging the ground asshown in Fig.

'7 if an unauthorized person attempts to move the 4 vehicle any forward 'movement will cause the jack arms to move to the position shown in Fig.

8, (however the wheels 32 willnot be'extend ed), for limiting the automobile from being moved.

For using the device as a. jack-to permit the automobile tobe driven with a flat tire-the jack; arm adjacent the flat tire is lowered to the posi-.

'tion shown in Figv 7 in a manner similar to that previously described. The proper knob 42of the,

flexible cables 4! isthen' rotated for rotating the ram M! to cause the wheel 32 to be extended from.

the jack arm to engage the ground when the I automobile moves forward asshown in Fig. 8 to permit the automobile to be driven to a service station or other convenient point for changing the tire. willbe prevented from moving beyond the vertical position bymeans of the jack arms 56' en- In both instances the jack arms it.

gaging the rear end of the cutout M and also the bolts 26' will engage -the-rear'end of the cut- 1 out 39 for holding the same in this vertical] position. I
